The title pretty much explains it.
Hubby replaced the battery today and the o2 sensor (based on a code 51 reading). He then tried to reset the code with the engine running and found out that he wasn't supposed to do that. I don't know if that is the problem, but now the car will not start. I think it is "dead" and doesn't even try to turn over. I will correct that if he tells me differently.
I need to be able to get to work and get my car tags, but cannot due to the check engine light.
Help, please :-).
